i have 2 issues. first, when i hit the brake pedal it vibrates and makes a grinding motor like sound and the wheels lockup. what part of the abs do i need to replace to fix this. next how often do i need to change the wheel bearings? also i need new hubs, i cant find the auto lokcing facory hubs anywhere online, so i was gonna go with the warn manual hubs. can anyone direct me to a good place to buy these and the service kit for them?

 

If you are looking for the factory hubs that came on your frontier... PM me your vin number and I'll get you a price.

 

first if you need any parts for your NISSAN frontier go to your local nissan dealership and go to the parts department and im 100% sure they can get you any replacement oem parts for your truck. Second your brake problem sounds like your front rotors are warped and the grinding noise is from your brake pads are down to nothing but metal and causing it to lock up. so check your front brakes immidiatly and your probaly going to need rotors and brake pads and hope that your calipers didnt get damaged. wheel bearings only have to be replaced when they start to go bad like making any noise like a chopping or whine noise.

 

i just replaced the brakes and rotors. its not that kind of noise. it sounds like the whirring of an electric motor. and the pedal vibrates. i think i want to put warn locking hubs, is there anything elese i would need to buy besides the hub itself since i am going from automatic to manual hubs

 

its possible that your hubs are bad but also you said you have abs so if it was under hard braking thats normal but if it does it all the time your rotors could be warped still even thought you bought new rotors, if they were not stored right on a shelf they can warp.
the 3 things that can cause this is
1. warped rotors
2. bad wheel bearings/hubs
3. normal abs pulsation under hard braking
